Key to Korean species of the genus Phylidorea Bigot

1. Wing with long radial sector (Rs) that is few times longer than stem of cell r 3 ( Figs. 1A , 2C , 4B , 5B )····· 2

- Wing with short radial sector (Rs) that just slightly exceeds length of cell r 3 stem ( Fig. 3B ) ··························· Phylidorea (Phylidorea) melanommata ( Alexander, 1921)

2. Body gray or brown ··················································· 3

- Body yellow or brownish yellow ( Fig. 2A ) ·············· 4

3. Prescutum and presutural scutum with three distinct polished black longitudinal stripes. Wing with dark spot in the middle between arculus and base of Rs, distinct dark areas surround base of Rs and cord ( Fig. 1A ). Male gonocoxite with large dorsal lobe ( Fig. 1B ). Larger species, male body length 9-10 mm ········· Phylidorea (Macrolabina) pernigrita ( Alexander, 1938)

- Prescutum and presutural scutum with very indistinct longitudinal stripes or stripes missing completely. Wing without dark spot between arculus and base of Rs, dark areas surrounding base of Rs and cord indistinct ( Fig. 4B ). Male gonocoxite without dorsal lobe ( Fig. 4C ). Smaller species, male body length up to 7.5 mm ··········· Phylidorea (Phylidorea) multidentata ( Alexander, 1938)

4. Abdomen with blackish lateral spots making inter- rupted line. Outer gonostylus of male genitalia with straight apical spine ( Fig. 2D ) ························· Phylidorea (Phylidorea) longicornis pietatis ( Alexander, 1950)

- Abdomen without dark lateral line. Outer gonostylus of male genitalia with strongly curved apex ( Fig. 5C ) ··· Phylidorea (Phylidorea) umbrarum ( Krogerus, 1937)
